The research assistants are those who received training in the previous project (MOST 102-2314-B-182-050-MY2) but investigator will recruit a new part-time research assistant, a nursing master student, to receive a one-month training course, including: the purpose of this study, the procedures for recruitment, test battery interview skills, the test battery scoring system, data collection using the EMS, data download from the EMS, and basic statistical techniques. Then the newly trained part-time assistant will go to the participating sites for observing at least three PWCIs, practicing the interview skills with dyads, and familiarize herself with the outpatient clinical operational system. The on-site participant physicians in the memory disorder clinics will receive a written letter to explain the purpose of this project and the eligible criteria for the dyads. These physicians will help investigators to identify eligible dyads, while trained research assistants will implement the intervention and education program. The part-time student assistant is responsible for data collection.
